AC Supply. What can I use for a throttle

Dan Padova ·
I have an AC supply. It's been sitting on myself for years. I would like to use it to power accessories. It puts out 20 VAC. What can I use as a throttle ?

Tin coating is used as a corrosion inhibitor, Even copper when subject to weather and moisture will form oxides and most likely sulfates, blue/green colors, which adds resistance to terminations. Automotive wiring subject to salts and corrosives, would do well to be tin plated, IMO. There are also additives, pastes, that can be use to increase/protect terminations in addition to the plating. Some crimp connectors will have the paste include as part of the connector. A 500 ft roll of single...

My LHS use 18 for everything so I followed suit. Solid wire is definitely much easier to hook up to accessories. I think 20 should also be fine. This comes from working with BOTH...... (stranded and solid)

A tip for using stranded wire for accessories, just tin the ends so the connections are using "solid" wire, but you have the flexibility of stranded wire.

I've tinned 24 awg stranded and, because of how thin it is / how few strands there are, I found that it snaps easily. Hence, why I now prefer solid for thin wire needs. Regarding Fleabay - every seller is obviously different, but I bought wire twice from 2 different sellers and in both cases it was old or poorly stored, brittle and crumbly. Caveat emptor. Peter

Any time you tin stranded wire, it is prone to breaking. The auto industry never tins or solders connectors for this reason. They crimp connections. One exception I found were BMW motorcycle harnesses. They bond multiple connection wires of the same circuit together inside a harness but only in a straight run. I think anytime there is movement or vibration, a soldered connector or wire end will tend to break.

Hmm... I have no such issue with tinning the ends of stranded wire, and I've been using that technique for years.

yes you can use it but typically accessories use 16 vac but not always, what is the amp rating on your power supply? Also it should either be fused or a circuit breaker in case of a short, you want the power to go off immediately, otherwise you could burn out your accessories, and if they are MTH they would have electronics boards and you would not want to burn out electrics as they get very expensive!

20 volts is fine, but how many amps? If it's not labeled, figure about 1 amp/lb. as a starting point. I have used 8 amp 22 volt industrial transformers for powering PM-1's for CAB-1 conventional control. It works well despite the 18 volt design of the TMCC system, but do so at your own risk.

Yikes. I'd want that off of me ASAP. OK, understood you've found a solution with your KW. Hijack alert. This being a discussion forum, if we're talking about powering accessories with a spare/unused fixed-output AC transformer, many newer accessories operate on DC input. For example, Menards, Lemax, Miller lighting products take 4.5V DC, animated mechanisms now routinely use DC gear-motor, and accessories with digital functionality must convert Accessory AC to a lower DC voltage such as 5V...

Nobody has suggested getting a TPC? That's what I have been using and building layouts with for years. They work great. Supposedly the new Power Masters have all the programming that the TPC did.

While the PM-1 PowerMaster can be used as a plug-n-play standalone with the 6 amp supply and a CAB-1, a TPC requires extra equipment and cabling.

Re: AC Supply. What can I use for a throttle

I'm not sure you are understanding what I would like to do. The power supply is an LGB 50110 6 Amp AC transformer. I need to vary the output voltage. LGB has a throttle but it changes the AC to DC at the throttle. Isn't there a device that would allow me to vary the voltage coming from the LGB power supply and keep it as AC ? Here are two photos showing the power supply and the throttle. As you can see, the transformer puts out AC only. The throttle, on the right, changes the AC power to DC...

I can think of a couple of ways to do this, but none of them are particularly practical. The first is to go super old school and use a rheostat. You waste a lot of power as heat, but it will get the job done. If you're looking to run accessories at a lower voltage this might work out. Next, you can use a Variac: This will vary the voltage on the input side of the transformer which will, in turn, adjust the output side. While it will work, even a cheap/used variac costs more than just buying...

JOHNGALTLINE gave a good rundown on alternate ideas for a throttle controller for fixed voltage output. I use a variable transformer feeding a salvaged step-down transformer on one of my layouts, which works well. I happened to have free secondhand parts on hand for that. Another possibility uses a bank of light bulbs connected in parallel, which as a group are connected in series with the circuit through the locomotive motor. Some of the earliest electric model trains used this method...

I understood perfectly, and now with some specific information, I will stick with using it to powering a PM-1 for CAB-1 conventional control(trains, accessories, lights, whatever you wish). The MTH Z controller will do the same thing, albeit with wires instead of wireless.

People always say "it's a personal preference," but that's silly. Because all my power drops are OGR stranded 14 AWG and had a bad experience with some old brittle solid 22AWG wire, I purposely stuck to stranded for everything. But, I realized brittle old solid isn't a good test case. And, as I've recently discovered, when working with fine wire, like 22AWG and finer, solid is much easier to work with because it doesn't fray or require tinning.

there is one thing about solid wire which you have to watch out for. when you strip the end, make sure you do not nick (even slightly) the wire itself. if you do, it will only a few bends and the single conductor will snap off. for very thin wires (< 26 ga), i use No-Nik strippers exclusively... cheers...gary

There is no fixed rule for what gauge of wire to use for track power or accessory power. It all depends on the length of wire and how many amps it will carry. A voltage drop calculator (Google it) can be used to figure adequate wire gauge for a specific application.

Re: Stranded VS Solid Hook Up Wire

overlandflyer ·
i often sit back and smile at these conversations, and i won't offer any counter argument, but if you actually did some practical research on this, 20 ga. wire in open air (how most train layouts are wired), will easily pass 5-6 amps which is a lot more power than any of my trains draw. AWG tables are hugely conservative for maximum power transmission (i.e. usually calculated as bundled wires over km distances) and even pushed to its maximum capacity 20 ga solid copper wire will drop less...

The only advantage for stranded wire is that it is more resistant to damage from frequent flexing. Solid wire is generally cheaper, and entirely satisfactory for your purpose. I recall once talking to a store clerk about solid vs. stranded wire of the same gauge for automotive applications. He said stranded wire was better because electricity travels on the surface of the wire, and stranded wire has lots more surface area. That's total BS !!!
Reply

Re: Stranded VS Solid Hook Up Wire

JohnGaltLine ·
Actually it isn't total BS, it just only applies to very high frequency currents. The effect is meaningless to anything in model trains or general household use, but it does exist. As far as layout wiring goes, use whichever you prefer. Solid is probably easier to get a clean strip and to attach to things, where as stranded is easier to fish through to the location. JGL

Re: Stranded VS Solid Hook Up Wire

Actually it's partially true. But not in this case. It's the omissions of details that were left out. Higher frequency current does travel on the surface of the wire. It's called skin effect. https://en.wikipedia.org/wiki/Skin_effect In the case of ordinary stranded wire, the surface area does not increase much since the wires are all shorted together. Stranded Litz wire does have a reduced resistance to higher frequency ac current because all the strands are insulated from each other.

Unless you have very long runs, I'd think that #16 would be sufficient. UL thinks it's good enough to plug into 15A branch circuits for extension cords! Obviously, if you run larger wire, you get less voltage drops.

For my track power I did use 14 gauge stranded wire. But for everything else, 14 gauge is too bulky to work with. I did check with the seller on the tinned wire. He assures me that it is tin coated copper. The reason I asked him is that $49.95 for 600 feet of 20 gauge copper wire on six rolls, each a different color, seems like a very good price.

Whoa Nelly, 16 gauge, really ? The wires that are supplied with almost all accessories can't be more than 22 gauge. The longest wire lead won't be any more than ten feet, and that's if I run from one end to the other, which is very unlikely.

Be careful of eBay wire. Make sure it's actually solid copper, much of the wire sold on eBay is aluminum that is copper plated.

Re: Stranded VS Solid Hook Up Wire

Good point. When you look at the charts, multiply the resistance listed by the expected amps on the wire and determine if you can stand the voltage drop. The voltage drop for our low 18 vac circuits are more critical than the 120 vac some of the charts' recommend gauges. In other words, a 2 vac drop on an 18 vac circuit is more significant than a 2 vac drop on a 120 vac circuit.

On a small layout where no more than ten feet tops, of wire is needed to hook up accessories and track, does it really make a difference if the wire is stranded or solid. I'm talking about 20 gauge wire. For one thing, solid wire lends itself more to traditional accessories.
